| Abstract: | Based on the characteristics of high integration level, small-size, small raise random error and simple design complexity of field programmable gate array (FPGA), the test system is developed to measure the phase random error and the drift error of twelve-channel location information and six-channel measuring velocity information simultaneously by designing FPGA chip. The reliability and stability of continuous wave interferometer are improved, and the working quality of channel is also improved. It is helpful for high precision outer trajectory measurement. |
